Ethane at 25oc combusts with 20% deficient (80% theoretical) air, also at 25oc, to produce a mixture containing co2, co, h2o, h2, o2, and n2. (note: 2 simultaneous equilibrium reactions! ) at temperature tp. the combustion occurs at 1 atm. part 1. determine the composition (molar fractions) at tp = 2000k, and determine the heat transfer q (in kj/kmol fuel).

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
